Should "warm" not have been accepted as a gloss for "t(h)e"?
Regarding weather, yes.
Not accepted tonight 13/02/16
Be sure to report it when opportunity allows for you.
Is "the" lenited for describing a feminine noun?
Wait, ‘we have hot weather today’ is English?
To this US English speaker, it sounds fine, if slightly uncommon.
So how do you say "we have warm weather today"
Use "te" or "brothallach". See http://www.teanglann.ie/en/eid/warm
Inniu sounds like inniumh in this recording
It's a common enough pronunciation of inniu.
While the examples at teanglann have the Munster speaker using that pronunciation, it is not restricted to Munster.
